Sarah K. Vann, 96, professor emerita of the University of Hawaii’s Library and Information Science Program in Honolulu, died May 25. She was a widely recognized authority in library history and international librarianship and a master teacher in library education. Vann also taught at Carnegie Library School of Pittsburgh, then at Columbia University and University of Texas at Austin. She was instrumental in establishing library schools at the State University of New York in Buffalo as well as overseas in the Philippines, Indonesia, and Pakistan. Her publications on Melvil Dewey and his contributions to librarianship as well as her extensive study of the Charles Williamson reports are considered enduring and seminal works providing detailed and scholarly commentary on the pre-Williamson and Williamson era of library service and library education.
